Channel Indicates a sequence error has been detected in
Sequence forward control channel. It this bit is set, an error may

have occurred in the control channel operation.

SDA Output
Delay
SDA Output Delay
This field configures output delay on the SDA output.
Setting this value will increase output delay in units of
50ns. Nominal output delay values for SCL to SDA
are:
00: 250ns (default)
01: 300ns
10: 350ns
11: 400ns
2
RW
Local Write
Disable
Disable Remote Writes to Local Registers through
Serializer (Does not affect remote access to I2C
slaves)
0: Remote write to local device registers (default)
1: Stop remote write to local device registers

Speedup
Speed up I2C Bus Watchdog Timer
0: Timer expires after approximately 1s (default)
1: Timer expires after approximately 50µs

I2C Bus
Timer
Disable
Disable I2C Bus Watchdog Timer.
When the I2C Watchdog Timer may be used to detect
when the I2C bus is free or hung up following an
invalid termination of a transaction. If SDA is high and
no signaling occurs for approximately 1 second, the
I2C bus is assumed to be free. If SDA is low and no
signaling occurs, the device will attempt to clear the
bus by driving 9 clocks on SCL

Device ID0
7-bit Remote Slave Device ID 0
Configures the physical I2C address of the remote
I2C Slave device attached to the remote Serializer. If
an I2C transaction is addressed to the Slave Alias
ID[0], the transaction will be re-mapped to this
address before passing the transaction across the
Bidirectional Control Channel to the Serializer.

7-bit Remote Slave Device ID1
Configures the physical I2C address of the remote
I2C Slave device attached to the remote Serializer. If
an I2C transaction is addressed to the Slave Alias
ID[1], the transaction will be re-mapped to this
address before passing the transaction across the
Bidirectional Control Channel to the Serializer.
